express创建ejs模块
准备工作
1、安装cnpm
npm install -g cnpm --registry=https://registry.npm.taobao.org
1、安装express环境
cnpm install express-generator -g
可通过以下代码查看所有可用的命令行参数
express -h
2、创建名称为 stuadmin 的 Express 应用。此应用将在当前目录下的stuadmin 目录中创建,并且设置为使用 ejs 模板引擎
express --view=ejs stuadmin
结果如下:
D:\>"node" "C:\Users\Direct\AppData\Roaming\npm\\node_modules\express-generator
\bin\express-cli.js" --view=ejs stuadmin
create : stuadmin\
create : stuadmin\public\
create : stuadmin\public\javascripts\
create : stuadmin\public\images\
create : stuadmin\public\stylesheets\
create : stuadmin\public\stylesheets\style.css
create : stuadmin\routes\
create : stuadmin\routes\index.js
create : stuadmin\routes\users.js
create : stuadmin\views\
create : stuadmin\views\error.ejs
create : stuadmin\views\index.ejs
create : stuadmin\app.js
create : stuadmin\package.json
create : stuadmin\bin\
create : stuadmin\bin\www
change directory:
> cd stuadmin
install dependencies:
> npm install
run the app:
> SET DEBUG=stuadmin:* & npm start
进入stuadmin文件夹,并安装所有组件
cd stuadmin
cnpm install
结果如下:
D:\>cd stuadmin
D:\stuadmin>cnpm install
√ Installed 6 packages
√ Linked 47 latest versions
√ Run 0 scripts
Recently updated (since 2019-11-07): 1 packages (detail see file D:\stuadmin\nod
e_modules\.recently_updates.txt)
√ All packages installed (54 packages installed from npm registry, used 1s(netw
ork 1s), speed 122.87kB/s, json 53(125.82kB), tarball 0B)
D:\stuadmin>
3、Express使用nodemon实现热更新
cnpm install --save-dev nodemon
结果如下:
D:\stuadmin>cnpm install --save-dev nodemon
/ [0/1] Installing is-buffer@^1.1.5platform unsupported [email protected] › chokida
[email protected] › fsevents@^1.2.7 Package require os(darwin) not compatible with your pl
atform(win32)

√ Linked 176 latest versions

√ All packages installed (192 packages installed from npm registry, used 5s(net
work 4s), speed 60.41kB/s, json 177(255.13kB), tarball 0B)
D:\stuadmin>
2、 修改配置文件,在package.json中的scripts中配置运行项即可
原来配置文件如下:
"scripts": {
"start": "node ./bin/www"
},
更改后如下:
"scripts": {
"start": "nodemon ./bin/www"
},
express就此安装完成!!!!
运行以下代码即可运行express应用并实现热更新
cnpm start
结果如下:
D:\stuadmin>cnpm start
> [email protected] start D:\stuadmin
> nodemon ./bin/www
D:\stuadmin>"node" "D:\stuadmin\node_modules\.bin\\..\[email protected]@nodemon\b
in\nodemon.js" ./bin/www
[nodemon] 1.19.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching dir(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node ./bin/www`
